SIMULATION OF AIR SPARGING ON GASOLINE SPILL. Jane and Bri. This experiment evaluates the effectiveness of air sparging, a clean-up process to the important environmental disasters of oil spills on land, on a micro-scale. Air was pumped through a layer of sandy-soil contaminated with gasoline into flask containing finely powdered carbon for about twenty four hours. Throughout the experiment, air flow rate was measured to check for consistency. Using Henry’s Law constant, density, permeability, and channeling, the applicability of air sparging in sandy-soil with gasoline contamination was determined to be partially successful. Out of 33.17 grams spilled, 4.59 grams were cleaned up, resulting in a 13.8% yield. Results support the conclusion that both gasoline and sandy-soil are favorable characteristics for an oil spill site. Future experiments could test the success of air sparging in different types of soils. Keywords: Air sparging; Henry’s Law; Permeability; Channels; Gasoline; Upper School Chemistry
